The Selective State Municipal Bond Portfolio seeks its investment objective by investing primarily in a universe of investment grade municipal securities, the interest on which is exempt from regular federal income tax. Municipal securities in which the Portfolio may invest include, among others, revenue bonds, general obligation bonds, industrial development bonds, municipal lease obligations, commercial paper, variable rate demand obligations and other instruments (including participation interests in such securities) issued by or on behalf of the states, territories, and possessions of the United States (including the District of Columbia) and their political subdivisions, agencies, and instrumentalities (“state issuers”). As of the date of this prospectus, the Advisor expects to emphasize investments in obligations issued by or on behalf of: (i) state issuers with no personal income tax (e.g., Wyoming, Washington, Tennessee, Texas, South Dakota, Nevada, Florida, and Alaska); (ii) state issuers that generally tax income earned from both in-state and out-of-state municipal securities (e.g., Iowa, Illinois, and Wisconsin); (iii) state issuers that do not tax income earned from in-state municipal securities and certain out-of-state municipal securities (e.g., Utah) and (iv) state issuers that do not tax income earned from in-state or any out-of-state municipal securities (e.g., District of Columbia). From time to time, the Advisor may emphasize investments in additional state issuers or reduce the Portfolio’s emphasis on certain state issuers without notice to shareholders. The interest on the municipal securities purchased by the Portfolio, in the opinion of bond counsel for the issuers and under current tax law, is exempt from federal income tax (i.e., excludable from gross income for individuals for federal income tax purposes but not necessarily exempt from state or local taxes). As a fundamental investment policy, under normal market conditions, the Portfolio will invest at least 80% of its net assets in municipal securities that pay interest exempt from federal income tax. The Portfolio does not currently intend to invest its assets in municipal securities whose interest is subject to the federal alternative minimum tax.

Generally, the Selective State Municipal Bond Portfolio will acquire obligations that mature within twenty years from the date of settlement, and in variable rate demand obligations with longer maturities. Under normal circumstances, the Portfolio will maintain a weighted average duration of more than three years but less than five years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the Advisor will focus investment in the longer-term area, otherwise, the Portfolio will focus investment in the shorter-term area of the eligible maturity range. If a security has been redeemed by the issuer at a date prior to the stated final maturity date for the purposes of the above duration restriction, the early redemption date shall be considered the maturity date regardless of the stated final maturity. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

At least 75% of the assets of the Selective State Municipal Bond Portfolio will be invested in municipal securities that, at the time of purchase, are rated in the top three credit-rating categories (e.g., Aaa, Aa and A for Moody’s Investor’s Service, Inc. (“Moody’s”) or AAA, AA and A for S&P Global Ratings (“S&P”) or Fitch Ratings Ltd. (“Fitch”), or an equivalent rating assigned by another nationally recognized statistical rating organization, or that are unrated but have been determined by the Advisor to be of comparable quality). No more than 25% of the Portfolio’s assets will be invested in municipal securities that, at the time of purchase, are rated in the lowest quarter of the investment grade spectrum (e.g., rated Baa1 to Baa3 (by Moody’s) or BBB+ to BBB- (by S&P or Fitch), or an equivalent rating assigned by another nationally recognized statistical rating organization, or that are unrated but have been determined by the Advisor to be of comparable quality). The fixed income securities in which the Portfolio invests are considered investment grade at the time of purchase.

Municipal securities are often issued to obtain funds for various public purposes, including the construction of a wide range of public facilities, such as bridges, highways, housing, hospitals, mass transportation facilities, schools, streets and public utilities, such as water and sewer works. Municipal securities include municipal leases, certificates of participation, municipal obligation components and municipal custody receipts. The Selective State Municipal Bond Portfolio may invest more than 25% of its assets in municipal securities issued to finance projects in a particular segment of the bond market including, but not limited to, health care, housing, education, utilities, and transportation. The Portfolio also may invest more than 25% of its assets in industrial development bonds.

The Selective State Municipal Bond Portfolio may (1) purchase certain municipal securities that are insured, (2) invest in municipal securities secured by mortgages on single-family homes and multi-family projects, (3) invest in pre-refunded municipal securities, (4) purchase tax-exempt municipal securities on a “when-issued” basis, and (5) use derivatives, such as fixed income related futures and options contracts, credit default swaps and interest rate swaps, to hedge against changes in interest rates. The Portfolio may also invest in exchange-traded funds (ETFs) to gain

exposure to the municipal bond market pending investment in municipal bonds. The Portfolio may also invest in money market funds. The Portfolio also may purchase or sell futures contracts and options on futures contracts, to hedge its interest rate exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure based on actual or expected cash inflows to or outflows from the Portfolio.

Although the Selective State Municipal Bond Portfolio attempts to invest all of its assets in tax-exempt securities, it is possible, although not anticipated, that a portion of its assets may be invested in securities that pay taxable interest, including interest that may be subject to the federal alternative minimum tax. These investments could generate taxable income for shareholders.
